Description
Oppfinnelsen angår en fremgangsmåte for fremstilling av en spole med foring for en brannresistent sandwichplate, en fremgangsmåte for fremstilling av brannresistent sandwichplate, og en slik brannresistent sandwichplate. The invention relates to a method for producing a coil with lining for a fire-resistant sandwich plate, a method for producing a fire-resistant sandwich plate, and such a fire-resistant sandwich plate.
Slike brannresistente sandwich-plater er til bruk som veggpaneler eller himlinger i interiører som er underlagt strenge brannregler, for eksempel interiører om bord på båter, oljeplattformer eller innen enkelte typer av bygninger. Such fire-resistant sandwich panels are for use as wall panels or ceilings in interiors that are subject to strict fire regulations, for example interiors on board boats, oil platforms or within certain types of buildings.
Forskjellige krav til veggpaneler og himlinger for slike formål, for eksempel til kostnader, vekt, varmeisolasjon, lydisolasjon, slitasje, bestandighet mot kjemikalier, estetisk verdi i tillegg til brannfarehensyn har ført til innførelse av sandwichplater av forskjellige typer. En sandwichplate av aktuell type, omfatter en kjerne av mineralull med stålplateforinger på begge sider. Av konstruksjonshensyn må mineralullkjernen anordnes med fibrene i kryss og foringene festet til kjernen ved hjelp av limstoff. Noen eksempler på denne type sandwichplater er forklart i den danske patentsøknad 3526/75 inngitt 4. august 1975. Different requirements for wall panels and ceilings for such purposes, for example for costs, weight, heat insulation, sound insulation, wear, resistance to chemicals, aesthetic value in addition to fire risk considerations have led to the introduction of sandwich panels of various types. A sandwich panel of the type in question comprises a core of mineral wool with steel plate liners on both sides. For construction reasons, the mineral wool core must be arranged with the fibers crossed and the liners attached to the core using adhesive. Some examples of this type of sandwich panels are explained in the Danish patent application 3526/75 filed on 4 August 1975.
Av estetiske årsaker er det vanlig å laminere stålforingene med plast eller belegge dem med PVC-folie. En PVC-folie med en tykkelse på 0,15 mm kan farges og struktureres til et attraktivt utseende. Selv om et produkt av denne type oppfyller de fleste gjeldende regler, vil plastlaminatet uunngåelig være en kilde til varmeutløsning og en kilde til skadelige og giftige gasser ved utsettelse for åpen ild. For aesthetic reasons, it is common to laminate the steel liners with plastic or cover them with PVC foil. A PVC foil with a thickness of 0.15 mm can be colored and structured to an attractive appearance. Although a product of this type meets most current regulations, the plastic laminate will inevitably be a source of heat release and a source of harmful and toxic gases when exposed to open flames.
Det er blitt foreslått å belegge stålforingene med et meget tynt lag av polymermateriale, for eksempel et lag med en overflatetykkelse på 0,03 mm for å minimere varmefrigjøringen og gassfrigjøringen under utsettelse for ild. Imidlertid har slike produkter ikke kunne bli godtatt på markedet på grunn av manglende estetisk utseende. It has been proposed to coat the steel liners with a very thin layer of polymeric material, for example a layer with a surface thickness of 0.03 mm, to minimize heat release and gas release during exposure to fire. However, such products have not been able to be accepted on the market due to a lack of aesthetic appearance.
Publikasjonen WO 95/30 552 inneholder forslaget med å bygge et sandwichpanel med en metallforing med en dekorativ farge, for eksempel en reproduksjon av et fotografi, eller kunstgjenstand. Ifølge denne publikasjon fremstilles platepanelet ved å stable sammen forskjellige komponenter, blant annet metallfolie, og et kalkerpapir og ved å trykke stabelen sammen ved hjelp av varme i 5-30 minutter, hvorved fargestoffet blir overført til plateover-flaten. The publication WO 95/30 552 contains the proposal to build a sandwich panel with a metal lining with a decorative color, for example a reproduction of a photograph, or art object. According to this publication, the plate panel is made by stacking together different components, including metal foil, and a tracing paper and by pressing the stack together using heat for 5-30 minutes, whereby the dye is transferred to the plate surface.
EP-A 00 72 461 inneholder et forslag for kontinuerlig trykking av en stålplate med en tykkelse på 0,75 mm ved hjelp av en overføringsprosess som finner sted mellom en presse med dobbelt bånd. EP-A 00 72 461 contains a proposal for the continuous printing of a steel plate with a thickness of 0.75 mm by means of a transfer process which takes place between a double belt press.
DE-C 26 42 350 og DE-C 29 14 704 angir forskjellige løsninger for fargestoff og DE-C 26 42 350 and DE-C 29 14 704 specify different solutions for dye and
trykkemetoder for tekstiltrykking. printing methods for textile printing.
Løsningene foreslått i den kjente teknikk ser ikke ut til å ha vunnet noen større andel av markedet for brannsikre paneler, antakelig på grunn av at fremstillingsmetodene er for tungvinte eller kostbare, eller kanskje fordi de ikke frembringer produkter som hek oppfyller alle aktuelle krav. The solutions proposed in the prior art do not seem to have won any greater share of the market for fireproof panels, presumably because the manufacturing methods are too cumbersome or expensive, or perhaps because they do not produce products that fully meet all applicable requirements.
Fremgangsmåten ifølge oppfinnelsen for fremstilling av en spole med foring for en brannresistent sandwichplate har de karakteristiske trekk som angitt i krav 1. The method according to the invention for producing a coil with lining for a fire-resistant sandwich panel has the characteristic features as stated in claim 1.
Denne gir en meget effektiv fremstillingsmetode for å konstruere en foring, ved hjelp av hvilken det er mulig å fremstille en sandwichplate som tilfredsstiller alle krav nevnt ovenfor og som utviser en ytelse under brannprøver som er overlegen de fleste plater på markedet i dag. Foringen trykkes ved hjelp av en overføringsprosess som muliggjør en lang rekke farger og mønstere. Overflatefinishen er meget bestandig mot slitasje og produktet kan skipes med et beskyttelsesbelegg som kan holdes på plass og således beskytte overflatefinishen helt til de avsluttende trinn i monteringen i rommet. This provides a very efficient manufacturing method for constructing a lining, by means of which it is possible to produce a sandwich panel which satisfies all the requirements mentioned above and which exhibits a performance under fire tests which is superior to most panels on the market today. The lining is printed using a transfer process which enables a wide range of colors and patterns. The surface finish is very resistant to wear and tear and the product can be shipped with a protective coating that can be held in place and thus protect the surface finish right through to the final stages of installation in the room.
Fremgangsmåten ifølge oppfinnelsen for fremstilling av en brannresistent sandwichplate har de karakteristiske trekk som angitt i krav 8. The method according to the invention for producing a fire-resistant sandwich panel has the characteristic features as stated in claim 8.
Denne tilveiebringer fremstilling av en sandwichplate som oppfyller de strengeste brannkrav og som også oppfyller flere andre krav nevnt ovenfor. Platen kan fremstilles på en relativt rimelig måte. This provides for the manufacture of a sandwich panel which meets the strictest fire requirements and which also meets several other requirements mentioned above. The plate can be produced in a relatively inexpensive way.
Sandwichplaten ifølge oppfinnelsen har de karakteristiske trekk som angitt i krav 9. The sandwich panel according to the invention has the characteristic features as stated in claim 9.
Denne plate oppfyller alle krav angående plater for bruk som innvendig veggpanel eller himling som forklart ovenfor. This board meets all the requirements regarding boards for use as an interior wall panel or ceiling as explained above.
Foretrukne utførelser vil fremgå av de avhengige krav. Preferred embodiments will appear from the dependent requirements.

I den viste stasjon på fig. 1, blir en stålplatebane 11 rullet ut fra spolen 9 og ført sammen med overføringsmaterialbanen 12 fra overføringsrullen 18 i en overflate-mot-overflate-kontakt mens den blir ført rundt en føringsrull 19 for å bringes i kontakt med overflaten av varmrullen 13. Reference is first made to fig. 1 for a brief explanation of the pressure transfer process according to the invention. In the station shown in fig. 1, a sheet steel web 11 is unrolled from the coil 9 and brought together with the transfer material web 12 from the transfer roll 18 in a surface-to-surface contact while being passed around a guide roll 19 to be brought into contact with the surface of the hot roll 13.
Baksidepapiret fra papirrullen 15 blir plassert på utsiden av stålplatebanen 11 og lagene holdes i overflatekontakt med hverandre ved hjelp av den sylindriske overflate av varmrullen 13, ved hjelp av trykk tilført av teppet 17 som følger en endeløs sløyfe og som holdes i spenn ved hjelp av et radialt overflatetrykk tilført banene, som er tilstrekkelig for å hindre glipp mellom overføringsmaterialet og stålplaten. The backing paper from the paper roll 15 is placed on the outside of the steel plate web 11 and the layers are held in surface contact with each other by means of the cylindrical surface of the hot roll 13, by means of pressure supplied by the carpet 17 which follows an endless loop and which is held in tension by means of a radial surface pressure applied to the webs, which is sufficient to prevent slippage between the transfer material and the steel plate.
I en foretrukket utførelse av oppfinnelsen er et trykk på 2-4 bar funnet å være effektivt. In a preferred embodiment of the invention, a pressure of 2-4 bar has been found to be effective.
Varmerullens diameter kan være 500 mm og rullen holdes fortrinnsvis ved en temperatur på 210°C. Overføringsmaterialets bane og stålplatebanen passerer rundt omtrent 80% av rullens omkrets og forlater varmerullen ved å gjøre en omdreining rundt en annen føringsrull 19. The diameter of the heating roller can be 500 mm and the roller is preferably kept at a temperature of 210°C. The transfer material path and steel sheet path pass around approximately 80% of the roll circumference and leave the heat roll by making a revolution around another guide roll 19.
Ved føringsrullen hvor banene forlater varmerullen blir overføringsmaterialets bane skilt fra stålplatebanen og viklet rundt overføringsopptaksrullen 14. At the guide roll where the webs leave the heat roll, the transfer material web is separated from the steel plate web and wound around the transfer take-up roll 14.
Varmerullens omdreiningshastighet tilpasses slik at den oppnår en kontakttid for hvert punkt på banen i størrelsesorden 20-30 sekunder, som er blitt funnet å være tilstrekkelig for å sikre en tilfredsstillende overføringstrykking ved hjelp av sublimasjon. I den foretrukne utførelse vil ekvivalenthastigheten for banebevegelsen være i området 3-5 m/min. The rotational speed of the heating roller is adjusted so that it achieves a contact time for each point on the web of the order of 20-30 seconds, which has been found to be sufficient to ensure satisfactory transfer printing by means of sublimation. In the preferred embodiment, the equivalent speed of the web movement will be in the range of 3-5 m/min.
For andre utførelser med større ruller, for eksempel opp til 2000 mm, settes omdreiningshastigheten tilsvarende lavere for å kunne opprettholde en kontakttid i størrelsesorden 20-30 sekunder. For other versions with larger rollers, for example up to 2000 mm, the speed of rotation is set correspondingly lower in order to be able to maintain a contact time of the order of 20-30 seconds.
Fargetettheten som tilføres i sublimasjonsprosessen, antas å være i området 1-5 g/m , fortrinnsvis 1-2 g/m . The color density supplied in the sublimation process is assumed to be in the range 1-5 g/m , preferably 1-2 g/m .
Etter at den varme stålplatebane 11 er blitt separert fra det brukte over-føringsmateriale, passerer den to føringsruller til og skilles fra baksidepapiret og fra teppet. Etter en rett bane blir stålplatebanen viklet på spolen 10 sammen med et mellomliggende folielag 7. After the hot steel plate web 11 has been separated from the spent transfer material, it passes two more guide rollers and is separated from the backing paper and from the blanket. After a straight path, the steel plate web is wound onto the coil 10 together with an intermediate foil layer 7.
I den foretrukne utførelse omfatter folien 7 en polyetylenfolie med en tykkelse på omtrent 20 ftm. Polyetylenfolien blir overflatebehandlet på den side som vender mot trykksiden på stålplatebanen ved hjelp av limstoff. Denne folietype er blitt funnet å gi tilstrekkelig beskyttelse for foringen og kan lett pilles av når det er ønskelig uten at den rives. Andre utførelser som tar sikte på en stabil beskyttelse, kan omfatte tykkere folier. In the preferred embodiment, the foil 7 comprises a polyethylene foil with a thickness of approximately 20 ftm. The polyethylene foil is surface-treated on the side facing the pressure side of the steel sheet web using adhesive. This type of foil has been found to provide adequate protection for the lining and can be easily peeled off when desired without tearing. Other designs aimed at stable protection may include thicker foils.
Stålplatebanen 11 forlater den oppvarmede rull med en temperatur på omtrent 210°C og kjøles ned i luften til en temperatur mellom 60 og 70°C ved det punkt hvor den vikles på foringsspolen 10. Den gjenværende varme på stålplatebanen underletter også limingen av beskyttelsesfolien. The sheet steel web 11 leaves the heated roll at a temperature of approximately 210°C and is cooled in the air to a temperature between 60 and 70°C at the point where it is wound onto the liner coil 10. The residual heat on the sheet steel web also facilitates the gluing of the protective foil.
Spolen av stålplaten 9 som brukes i denne fremstilling, omfatter en stålplate med en tykkelse i området 0,5 - 0,7 mm, idet stålplaten er blitt forhåndsbehandlet med et overflatebelegg. Dette overflatebelegg som påføres i et opplegg som ikke er vist på tegningene, omfatter et polyesterbasert materiale med innbakte sfærer av polyamid. I den foretrukne ut-førelse blir et basislag med polyestermateriale påført stålplaten og herdet, og et topplag med polyester med nedhengende polyamidsfærer blir etterpå påført og herdet. The coil of steel plate 9 used in this production comprises a steel plate with a thickness in the range of 0.5 - 0.7 mm, the steel plate having been pre-treated with a surface coating. This surface coating, which is applied in an arrangement not shown in the drawings, comprises a polyester-based material with baked-in spheres of polyamide. In the preferred embodiment, a base layer of polyester material is applied to the steel plate and cured, and a top layer of polyester with hanging polyamide spheres is subsequently applied and cured.
Basislaget omfatter omtrent 15 g/m polyesterbasert materiale mens topplaget omfatter et tillegg på omtrent 15 g/m<2> polyesterbasert materiale med 3-4 g/m<2> polyamidsfærer. Med denne fremgangsmåte blir polyamidsfærene anordnet vesentlig på den øvre overflate hvor de tjener til å frembringe et attraktivt utseende og sikre slitasjemotstand mens polyestermaterialet kan oppfylle formålet med å feste sfærene, beskytte stålplaten og neste fargestoffet som påføres under overflatetrykkingen. The base layer comprises approximately 15 g/m of polyester-based material while the top layer comprises an addition of approximately 15 g/m<2> of polyester-based material with 3-4 g/m<2> of polyamide spheres. With this method, the polyamide spheres are arranged substantially on the upper surface where they serve to produce an attractive appearance and ensure wear resistance, while the polyester material can fulfill the purpose of attaching the spheres, protecting the steel plate and next the dye that is applied during the surface printing.

Fig. 3 shows a sandwich plate 1 according to the invention in a plan view to show just one example of the pressure indicator 5.
Sandwichplaten 1 ifølge oppfinnelsen fremstilles i en bearbeidingslinje hvor foringsspolen vikles ut, behandles med polyuretanlimstoff og kuttes i deler med passende format. Da sandwichplaten fortrinnsvis fremstilles med like eller identisk motstående sider, er det foretrukket å skjære ut par med identiske foringsemner. The sandwich panel 1 according to the invention is produced in a processing line where the lining coil is unwound, treated with polyurethane adhesive and cut into parts of suitable format. As the sandwich panel is preferably produced with equal or identical opposite sides, it is preferred to cut out pairs of identical lining blanks.
En plate av mineralull som er innrettet slik at fibrene strekker seg generelt i kryss og skåret i passende format, plasseres på et foringsemne av et par, mens det andre emne vrenges og plasseres på toppen. Sammenstillingen blir så varmetrykket for å herde polyuretanlimstoffet og kantene blir trimmet. A sheet of mineral wool arranged so that the fibers run generally crosswise and cut to the appropriate format is placed on one liner blank of a pair, while the other blank is turned over and placed on top. The assembly is then heat pressed to harden the polyurethane adhesive and the edges are trimmed.
Platene ifølge oppfinnelsen fremstilles i bredder fra 100 mm til 1250 mm og i lengder fra 800 mm til 10.000 mm. Sandwichplatenes tykkelse ifølge oppfinnelsen varierer fra 25 mm til 100 mm, de fleste tykkelser er på 25 mm eller 50 mm. Andre dimensjoner kan fremstilles ved hjelp av liknende metoder.
